1 '0 all whom it may concern:

Be it know-n that I, EDWARD PRUTZMAN, a citizen of the United States, residing at Lewisburg, in the county of Union and State of Pennsylvania, have invented a new and useful Device for Opening 'Envelops;

' and I do hereby declare the following to be opener.

a full, clear, and exact description of the invention, such as will enable-others skllled in the art to which it appertains to make and use the same.

This invention relates to a new and useful device for opening envelops and subsequently removing the contents thereof, and as an object of the invention, it is the aim to provide simple, efiicient and practical means for accomplishing the foregoing purpose.

In practical fields the details of construction may necessitate alterations, falling within the scope of what is claimed.

The invention comprises further features and combination of parts, as hereinafter set forth, shown in the drawings and claimed.

In the drawings: Figure 1 is a view in elevation of an envelop showing the im-.

proved device as applied thereto for opening the same and subsequently removing the contents. Fig. 2 is a sectional view on line 22 of Fig. 1. Fig. 3 is a plan view of the blank, showing the envelop opener (which in this case consists of a thread on the inner face of the blank) as applied to the envelop blank. Fig. 4 is a view of the envelop, showing the same having been opened', and the contents partly removed.

Referring more especially to the drawings, 1 designates the blank of the envelop having the usual bottom flap 2, the end flaps 3, and the closure flap 4. In forming the envelop inreadiness for its contents, the two end flaps are first folded, and to them the bottom flap 2 is connected adhesively as shown at 5, and the closure flap 4, after'the contents have been placed within the envelop is closed and adhesively connected at 6 to the end flap.

When constructing the blank, a piece of endless thread is employed, to be used as an ranged angularly and crossing one another. The portion 8 of the thread passes through an opening 10 centrally of one of the end flaps 3 where it folds, and is disposed ad- Portions 7 and 8 of the-thread are adjacent to the inner face of the body 9 of the envelop blank, said portions being ar-' jacent the fold 11 upon the outside, and extends to the corner 12 intermediate one of the end flaps 3 and the closure flap 4. The thread, as shown at 13, extends from the corner 12 and is arranged detachably adjacent the inner face of the body 9 of the envelop blank, and disposed angularly, and merges into theportion 7, as shown, forming a knot-14 which is on the outside of the envelop. The portion 7 of the thread engages the corner 15 between one of the flaps 3 and the bottom flap 2, and passes adjacent -the fold 11 upon its exterior, as shown at 16, and then through the opening 10, and from the opening 10 the portion 17 of the thread is arranged detachably adjacent the inner face of the body portion 9- of the envelop blank. The portion 17 of the thread engages the corner 18 adjacent or between the closure flap land the other end flap 3, and passes upon the outside of the envelop adjacent the fold l9, and subsequently engages the corner 20 between one of the flaps 3 and the bottom flap 2, and after engaging said corner of the blank, that portion 21 of the thread merges into the portion or part 8 of the thread. By this construction and arrangement of the thread opener, it will be seen that upon inserting the contents in the envelop, said contents will assume a position between the parts or portions 7 and 8, and the parts or portions 13 and 17 and after which the closure flap 4 is closed. Upon desiring to open the envelop, the thread at 11 and 16 and at 21 is pulled in opposite directions, the thread acting to cut the folds between the end flaps and the body of the envelop. Then by pulling on the thread from one end of the envelop, of from the otherend, the contents ma} be extracted.

The invention having been set forth, what is claimedas new and useful is In combination with an envelop, an opener therefor comprising a thread having angularly arranged intersecting parts arranged adjacent the inner face of the body of the one direction, one of the angular portions adjacent the other end flap, and one of the angular portions adjacent the body of the envelop merging together and forming a single loop ad'iacent the exterior of the fold of the other end flap, said single loop designed to be pulled.
